Which of the following thickens sauces and soups due to its ability to absorb water and form a gel?

निम्नलिखित में से कौन-सा पदार्थ पानी को अवशोषित करके जेल (Gel) बनाता है और सॉस तथा सूप को गाढ़ा करता है?

Options / विकल्प

A. Sugar (चीनी)

B. Oil (तेल)

C. Salt (नमक)

D. Starch (स्टार्च)


Correct Answer / सही उत्तर

D. Starch (स्टार्च)


Detailed Explanation / विस्तृत व्याख्या

Hindi

स्टार्च (Starch) एक जटिल कार्बोहाइड्रेट है जो मकई, आलू, गेहूं और चावल जैसे पौधों में पाया जाता है। जब स्टार्च को पानी के साथ गर्म किया जाता है, तो इसके कण पानी को अवशोषित कर फूल जाते हैं और एक गाढ़ा जेल जैसा मिश्रण बनाते हैं। इस प्रक्रिया को जेलैटिनाइजेशन (Gelatinization) कहा जाता है।

इसी गुण के कारण स्टार्च का उपयोग:

  • सूप को गाढ़ा करने में
  • सॉस बनाने में
  • ग्रेवी तैयार करने में
  • पुडिंग और कस्टर्ड बनाने में

किया जाता है।


English

Starch is a complex carbohydrate found in plants such as corn, potatoes, wheat, and rice. When heated in water, starch granules absorb water, swell, and eventually form a gel-like structure. This process is known as gelatinization.

Because of this property, starch is commonly used to thicken:

  • Soups
  • Sauces
  • Gravies
  • Custards and puddings

Why Other Options Are Incorrect / अन्य विकल्प गलत क्यों हैं?

A. Sugar (चीनी)

❌ Incorrect

  • Sugar dissolves in water but does not form a gel by absorbing water.
  • It is mainly used as a sweetener.

B. Oil (तेल)

❌ Incorrect

  • Oil is hydrophobic (water-repelling).
  • It does not absorb water and cannot form a gel.

C. Salt (नमक)

❌ Incorrect

  • Salt dissolves in water and enhances flavor.
  • It does not act as a thickening agent.

One-Liner / एक पंक्ति में

Starch thickens sauces and soups because it absorbs water and forms a gel during gelatinization.

स्टार्च पानी को अवशोषित करके जेल बनाता है, इसलिए यह सॉस और सूप को गाढ़ा करता है।
